Hebrews 3:7-11American Standard Version (ASV)
7 Wherefore, even as the Holy Spirit saith,
To-day if ye shall hear his voice,
8 Harden not your hearts, as in the provocation,
Like as in the day of the trial in the wilderness,
9 Where your fathers tried me by proving me,
And saw my works forty years.
10 Wherefore I was displeased with this generation,
And said, They do always err in their heart:
But they did not know my ways;
11 As I sware in my wrath,
They shall not enter into my rest.
